Answer:
y = x-4
Step-by-step explanation:
y = -x-5
Slope of line is -1.
Slope of perpendicular to line is 1.
Point-slope equation for line of slope 1 that passes through (6,2):
y-2 = 1(x-6)
Rearrange equation to slope-intercept form:
y = 1(x-6) + 2
y = x-4
I'm assuming you mean Cartesian plane. It is the same as a coordinate plane. There are two perpendicular lines with an x (horizontal) and y (vertical) axis.
